Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention.

The existing front panel mainly includes three types as shown in fig. 1, including a front panel type 1 having a UART interface, a front panel type 2 having an IIC interface, and a front panel type 3 having a GPIO interface. The front panel type 3 only needs simple indication lamps for displaying, so that the front panel type 3 is only connected with a mainboard in a butt joint mode through simple GPIO signals for controlling lighting, and the front panel type 3 is mainly communicated with the mainboard through 2 data signals of the hard disk and the network indication lamps.

The front panel type 1 needs to support multiple functions such as restart, key pressing, infrared and the like, so the front panel realizes the functions through a single chip microcomputer, most of communication interfaces butted with a main board are UART interfaces, namely UART (universal asynchronous receiver transmitter), the UART interfaces are serial communication modes, and the UART interfaces comprise TX and RX2 data signals.

The function of the front panel type 2 is relatively simple, but not only limited to the requirement of indicating lamp display, a simple single chip microcomputer supporting IIC communication may be selected for realization, at this time, the front panel type 2 is butted with a main board to form an IIC interface, an IIC bus is a two-wire serial multi-host bus, 2 signals including clock and data are output in a leakage mode, and a VDD power supply is pulled up during circuit design.

In order to adapt to front panels which can be butted, all external interfaces reserved on a main board in the prior scheme are used for adapting to various types of front panels, only one type of front panel is butted in product assembly, one type of front panel is actually used, and other interfaces are not used, so that the material cost of equipment is undoubtedly increased.

The present application provides a communication interface of a motherboard as shown in fig. 2, where the communication interface 20 of the motherboard includes: the communication method comprises a first interface multiplexing pin 21, a second interface multiplexing pin 22, a power pin 23 and a ground pin 24, wherein after the front panel is connected with the main board through a communication interface of the main board, power is supplied to the front panel through the power pin 23 and the ground pin 24, and data interaction between the main board and the front panel is realized through additionally adding two signal lines between the first interface multiplexing pin 21 and the second interface multiplexing pin 22 and pins of the front panel interface, and a flow of the communication method based on the main board communication interface provided by the application is shown in fig. 3.

Step 301: after the communication interface of the mainboard is plugged into the front panel, the level information of the data signal of the front panel is obtained through the first interface multiplexing pin and the second interface multiplexing pin.

Step 302: and determining the interface type of the mainboard according to the level information, and communicating with the front panel through a communication protocol corresponding to the interface type of the mainboard.

In one embodiment, the communication interface of the motherboard shown in fig. 4 further includes: power-off control pins 25, the interface types include: the power-off control pin is a pin specific to the UART interface and is used for controlling the power-off of the main board reversely, so that the communication interface shown in fig. 4 can realize the switching of three different interface types.

It should be noted that, when the communication interface of the motherboard is multiplexed, the embodiment shown in fig. 5 is taken as an example, but in specific application, the positions of five pins may be set according to actual requirements, where pin 5 in fig. 5 is a power supply pin, pin 4 is a ground pin, and pin 3 is a pin for a specific function of the UART interface, and is used for controlling the power failure of the motherboard reversely, and the front panel with the IIC and GPIO lighting functions does not have this function. In fig. 5, pins 1 and 2 are interface multiplexing pins, and may be adapted to a GPIO interface, a UART interface, and an IIC interface according to specific front panel types, where data signals corresponding to the interface multiplexing pins are shown in table 1, and level information of pins 1 and 2 corresponding to different communication modes is shown in table 2.

TABLE 1

Pin	UART communication	GPIO communication	IIC communication
				PIN_1	RXD_FRONT	NET_LED	IIC_SCL
PIN_2	TXD_FRONT	HDD_LED	IIC_SDA

TABLE 2

According to the convention in the table, when the front panel type is GPIO, a pull-down resistor is needed when the front panel IO is designed correspondingly, the default level is 00, when the front panel type is IIC, the clock and data signals are output in a leakage mode according to the IIC mentioned above, the clock and data signals need to be pulled up to a VCC power supply when the front panel IO is designed, according to the characteristic, the front panel can be arranged to be pulled up to VCC corresponding to the IIC interface, namely, the level of the 1 st pin and the level of the 2 nd pin are 11. Therefore, if the FRONT panel is of the IIC interface type, the default level acquired by the main control terminal is certainly 11, when the FRONT panel type is UART, the TXD _ FRONT (the RXD signal at the end of the FRONT panel singlechip to which the CPU is connected) corresponding to the CPU is pulled up to VCC, and the RXD _ FRONT sends a signal to the singlechip, and the default is usually output high level, that is, the 1 st and 2 nd pin levels may be 10 or 11, so that it is difficult to distinguish the UART interface or the IIC interface from the 1 st and 2 nd pin levels, a protocol needs to be selected to try to communicate and respond, and the UART interface or the IIC interface is determined according to the response result.

In one embodiment, the step 302 of confirming the communication mode according to the level information may be specifically executed by the flow of fig. 6:

step 601: judging whether the level information of the data signal is a high level or a low level; if the level information is low level, step 602 is executed, and if the level information is high level, step 503 is executed.

Step 603: and communicating with the front panel by adopting a communication protocol of an interface type corresponding to the high level.

The communication interface can be reused in the communication mode, the material cost is reduced, and the utilization rate of the interface is improved.

It should be noted that when the communication protocol of the interface type corresponding to the high level is used to communicate with the front panel, the determination may be performed in two ways.

Step 802: judging whether the communication with the front panel is successful or not according to the second detection information; if yes, go to step 803, otherwise go to step 804.

Step 803: communicate with the front panel via the second communication protocol.

Step 804: and reconfiguring the communication interface to adopt a second communication protocol corresponding to the UART interface type to send first detection information to the front panel.

Step 805: judging whether the communication with the front panel is successful or not according to the first detection information; if yes, go to step 806, otherwise go to step 807.

Step 806: and communicating with the front panel through the first communication protocol.

Step 807: determining the front panel anomaly.

When the mainboard acquires high-level information in the first mode or the second mode, which communication protocol is selected to communicate with the front can be accurately judged, so that the multiplexing type of the interface is acquired.
